2. Description of Related Art

As people nowadays are busy in work and life, for convenience in cleaning tasks, different kinds of vacuum cleaners are provided. Among the vacuum cleaners, a conventional self-propelled vacuum cleaner is particularly favored by the users because the conventional self-propelled vacuum cleaner can move on the ground automatically to provide a vacuuming-cleaning operation. The conventional self-propelled vacuum cleaner has a casing, a control module and a vacuuming module. The casing has a bottom, an annular sidewall, multiple wheels and at least one side brush. The wheels are rotatably mounted on the bottom of the casing. The at least one side brush is rotatably mounted on the annular sidewall of the casing. The control module is mounted in the casing to control the rotation of the wheels. The vacuuming module is connected to the casing and has a fan, a connecting tube and a dust-collecting element. The connecting tube is connected to the fan and the dust-collecting element. The dust-collecting element has a vacuuming hole extending out of bottom of the casing.

In use, the conventional self-propelled vacuum cleaner can only be used to clean the flat areas. When the conventional self-propelled vacuum cleaner moves to a corner, the vacuuming hole of the dust-collecting element that is disposed on a center of the casing and cannot suck dust from the corner. The conventional self-propelled vacuum cleaner needs to use the at least one side brush to sweep the dust to the vacuuming hole of the dust-collecting element. However, the sweeping force of the at least one side brush is not strong enough to sweep all of the dust to the vacuuming hole of the dust-collecting element, and this will affect the cleaning effect of the conventional self-propelled vacuum cleaner. Furthermore, the conventional self-propelled vacuum cleaner cannot be used to vacuum dust on the vertical curtains, on the screen window, or in the car, and the user needs to buy another kind of conventional cleaning device. As such, the conventional self-propelled vacuum cleaner has insufficient and limited applicability.

To overcome the shortcomings, the present invention provides a self-propelled vacuum cleaner to mitigate or obviate the aforementioned problems.
